I really like the lines on this piece. My ONLY nit, is on her face. What would be her right side, is bowled out a little on the cheek and her mouth might be just a tad big. My eye went straight to that part of the piece. Perhaps slimming her cheekbone and making it a little higher and dropping the size of her mouth to compensate. I love the hair, the pose, the proportions, the line quality.. everything else. I would also consider maybe pushing her hair back where it meets her breast just enough that you don't run into a slight tangent there. It might help add to this piece visually.
